HaLeivi – Sorry, Rav Saadiah, you’re right. I may also have worded it a little wrong, what I meant was that he says the belief comes entirely from avodah zorah belief systems and is as such completely incompatable with Judaism. Also Rav Crescas does not say that, what he says (according to the best of my understanding) is that he does not believe in it despite the fact that people tell him that it is kabbala, however if someone can prove the truth of it to him then he would.
Derech Hamelech – And the mekor of the “echod mimeforshei haRamban” is? I didn’t think you were making it up – I had heard the claim long before I’d heard of the CR. What I was saying is that I find it extrememly hard to believe historically. Could you please answer me how when the Rambam, the famous rationalist who dismissed much of the supernatural as non-existent, suddenly turned around completely and said that he now did in fact believe in it absolutely no-one batted an eyelid. Nobody even took the time to write a letter to their acquaintance saying “have you heard the news?”?! How is there not a single note of this momentous chazoro?
